Description: 

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate Earth Observation Metadata Profile of the OGC Observations and Measurements (O&M) Standard.

The Earth Observation (EO) Metadata profile of Observations and Measurements is intended to provide a standard schema for encoding Earth Observation product metadata to support the description and cataloguing of products acquired by sensors aboard EO satellites.

EO products are differentiated by parameters such as the date of acquisition and the image footprint as well as characteristics pertaining to the type of sensor, the type of platform, the applied processing chain, and more. This candidate standard identifies the metadata elements that enable the robust description of general EO products and defines specialisations for specific thematic classes of EO products, such as optical, radar, atmospheric, altimetry, limb-looking and systematic/synthesized EO products. In addition, this document describes the mechanism used to extend these thematic schemas for specific EO missions.

Version 1.0 of the EO Metadata profile of O&M is an OGC Implementation Standard that was adopted in 2012. Since then the standard has been implemented by the EO ground segments of a number of EO missions. During these implementations, a number of improvements and corrections have been identified. The proposed version 1.1 addresses these corrections and improvements.

The documents for the candidate OGC Earth Observation Metadata profile of Observations & Measurements Standard are available below for review and comment.

Description: 

The Open Geospatial Consortium (OGC®) has issued a Request for Quotation/Call for Participation (RFQ/CFP) in the OGC Testbed 11 Interoperability Testbed.

Testbed 11 sponsors have documented interoperability requirements and objectives for this testbed activity. Organizations selected to participate in Testbed 11 will develop solutions based on the sponsors’ use cases, requirements and scenarios, which are described in detail in the RFQ/CFP. Participants’ solutions will implement existing OGC standards as well as new prototype interface and encoding specifications introduced or developed in Testbed 11. Prototype specifications may ultimately become OGC standards, revisions to existing OGC standards, or best practices for using OGC standards.

Testbed 11 Sponsors include:

  • European Organization for the Safety of Air Navigation (EUROCONTROL)
  • Land Information New Zealand (LINZ)
  • National Aeronautics and Space Administration (NASA)
  • National Geospatial-Intelligence Agency (NGA)
  • UAE Ministry of Interior Abu Dhabi Police GIS Center for Security (UAE - ADP GIS CS)
  • UK Defense Science and Technology Lab (UK-DSTL)
  • US Department of Homeland Security (DHS)
  • US Geological Survey (USGS)

The RFQ/CFP and information about Testbed 11 are available below. Responses are due by 5:00 pm EST on 21 November 2014.

An IP Program and Testbed 11 Q&A Webinar will be held on 30 October 2014 at 10 am EDT ( Check your local time ). Register here: https://www4.gotomeeting.com/register/287254487.

For the most efficient use of this webinar, please send your questions in advance to techdesk [at] opengeospatial.org. You are also invited to follow us on twitter, Linkedin or Facebook to stay updated on the Q&A Webinar, clarifications to requirements, kickoff details, etc.

The OGC Testbed 11 Kickoff Workshop is planned for 12-14 January 2015 at George Mason University (GMU), Fairfax Campus in Northern Virginia. Additional details for the Kickoff Workshop will be provided later.

Testbed 11 focuses on spatial communication requirements that emerge when a population is displaced due to coastal inundation. Testbed participants addressing requirements in this scenario will attempt to meet these goals:

  • Advance OGC Architecture with respect to REST and SOAP design patterns for synchronization of geodata across data stores, as well as storage and synchronization of geodata in GeoPackages;
  • Evaluate approaches to JSON and GeoJSON encodings as well as vector data and image streaming in the OGC standards framework;
  • Integration of high-resolution simulation models into geospatial infrastructures
  • Advance use of Linked Data and Semantic Enabling of OGC Web Services, with a special focus on Hydrographic Data;
  • Advance use of OGC Catalog Services;
  • Advance use of spatially enabled Social Media data;
  • Advance use of a common symbology that can be used to share common operational pictures in an international environment;
  • Advance compliance tests for the OGC Web Feature Service and Catalog 3.0 Service interface standards;
  • In Aviation, advance a Digital NOTAM validation service and enrichment service and advance use of Aviation Feature Schema (AFX). Also develop guidance on using geometrical constraints in the Semantics of Business Vocabulary and Rules (SBVR) (an Object Management Group standard).

Those testbed goals sort into these technology threads:

  • Cross-Community Interoperability (CCI) Thread
  • Urban-Climate Resilience (UCR) Thread
  • Geospatial Enhancements for NIEM (Geo4NIEM)

This cutting edge technology work has enormous potential for testbed stakeholders – both the technology users and the technology providers – and for the world at large. The return on the shared investment in spatial standards is extraordinary, much like the return on the original shared investments in http and html. Technology providers gain market exposure, market intelligence, and a chance to quickly take advantage of the business opportunities that arise with the introduction of new standards and associated technical capabilities.

If you want to learn more about this opportunity, please contact  Lew Leinenweber , Director Interoperability Programs (techdesk [at] opengeospatial.org). See http://www.opengeospatial.org/ogc/programs/ip for more information about the 15 year old OGC Interoperability Program in which OGC testbeds, pilot projects and interoperability experiments are organized, planned and managed.

Description: 

The Open Geospatial Consortium (OGC®) membership seeks public comment on the candidate OGC Web Processing Service (WPS) Version 2.0 Interface Standard.

In many cases geospatial or location data, including data from sensors, must be processed before the information can be used effectively. The OGC Web Processing Service (WPS) Interface Standard provides a standard interface that simplifies the task of making simple or complex computational processing services accessible via web services. Such services include well-known processes found in spatial extract, transform, and load (ETL) software and GIS software as well as specialized processes such as coordinate transformation and spatial and temporal modeling and simulation. Moreover, the WPS standard supports both immediate processing for computational  tasks that take little time and asynchronous processing for more complex and time consuming tasks. While the OGC WPS standard was designed with spatial processing in mind, it can also be used to readily insert non-spatial processing tasks into a web services environment.

This WPS 2.0 candidate standard is a revision of WPS 1.0 (published in 2007). It incorporates change requests that have been submitted since the release of WPS 1.0 and provides improved support for process cataloguing and retrieval.

The 30 day public comment period for the candidate OGC Web Processing Service (WPS) Version 2.0 Interface Standard ends 25 September 2014 [ extended until 9 October 2014 ]. After the OGC’s WPS Standards Working Group has addressed comments received in response to this Request for Comments (RFC) the draft document will be submitted to the OGC Technical Committee and Planning Committee for their review and possible approval as an adopted OGC Standard.

The WPS 2.0 candidate standard doscument can be downloaded below:

OGC calls for comment on candidate Moving Feature Encoding standard

Status: 
Please note:  This Request is scheduled to close on 23 August 2014.
Open Date:

Closing Date: 
Sat, 08/23/2014 - 04:00
Description: 

The OGC seeks public comment on a candidate OGC® Moving Feature Encoding Standard. Part I of this candidate standard provides a standard way of encoding moving feature data in an XML encoding in the form of an OGC Geography Markup Language (GML) application schema. Part II provides a standard way of encoding moving feature data in a simple CSV (comma-separated value) format.

The candidate OGC® Moving Feature Encoding Standard is available below. Comments are due by 23 August 2014.

The advance of mobile computing and internet-connected sensors (including sensors and GPS transponders in cell phones and notebook computers) brings with it a rapid rise in applications for moving feature data, typically representing vehicles or pedestrians. Many innovative moving feature applications will require the overlay and integration of moving feature data from different sources. Examples can easily be imagined for disaster risk management, traffic information services, security services, navigation for robots, aviation or maritime traffic monitoring, and wildlife tracking and conservation. Most current applications, however, are limited to single-source moving feature data.

More efficient moving feature data exchange will result in a requirement for massive data handling. The CSV style encoding provides an efficient and easily understood standard for encoding lightweight data records, which will be important for many applications involving large data volumes and real-time response. The GML application schema style encoding for Moving Features provides for the encoding of more complex spatial information.

This standard addresses only “rigid” moving features, such as vehicles, as opposed to those that deform, such as flood water, and it does not address moving features whose descriptions contain other moving features that must be updated as the feature moves, such as control surfaces on an unmanned aerial vehicle (UAV). It also is for archived Moving Feature data only, and not for live feeds from sensors.

Description: 

The Open Geospatial Consortium (OGC®) membership seeks public comment on the candidate OGC GML Application Schema - Coverages – JPEG2000 Coverage Encoding Extension (abbreviated as “GMLCOV for JPEG2000”).

GIS coverages (including the special case of Earth images) are two- (and sometimes higher-) dimensional metaphors for phenomena found on or near a portion of the Earth's surface. Coverage instances may be encoded using the OGC GML Application Schema – Coverages (GMLCOV) Encoding Standard, which is based on the Geography Markup Language (GML), an XML grammar written in XML Schema for the transport and storage of geographic information. GMLCOV for JPEG2000 specifies an encoding of GML coverages for the JPEG2000 data exchange formats for still imagery (i.e. JPC, JP2, JPX). This document is the basis for the GML in JPEG2000 encoding standard v2.0 and a future format extension for WCS.

This candidate standard can be downloaded below.

Suggested additions, changes, and comments on this candidate standard are welcomed and encouraged. Such suggestions may be submitted by 20 August 2014.

Description: 

The Open Geospatial Consortium (OGC™) membership seeks public comment on the candidate OGC Web Map Tile Service Simple Profile of the OGC Web Map Tile Service (WMTS) Interface Standard.

Current OGC WMTS Interface Standard implementations return small, pre-generated map images (e.g., PNG or JPEG) or reuse cached map requests that follow a discrete set of tile matrices. The standard defines rules for multiple request/response patterns, including KVP, REST and SOAP.

The candidate OGC WMTS Simple Profile aligns the currently implemented and more comprehensive OGC WMTS Interface Standard to other popular tile initiatives that are less flexible but widely adopted. Server implementations of this profile should share two common sets of tile matrices and have a mandatory RESTful interface, though other interfaces are allowed. The WMTS Simple Profile is designed to allow developers to more quickly implement the WMTS standard.

Description: 

The Open Geospatial Consortium (OGC®) Membership seeks public comment on a new version of the OGC Catalogue Service interface standard. This standard specifies a design pattern for defining interfaces to publish and search collections of descriptive information (metadata) about geospatial data, services and related information objects.

There are three documents being considered. The first document defines the General Model for a catalogue service. The General Model is technology neutral. Therefore, the second document describes the rules for deploying a Catalogue Service in the HTTP environment, also known as Catalogue Service for the Web, or CS-W. The third document contains a detailed Abstract Test Suite for conformance classes described in the CS-W document. The main changes from version 2.0.2 include the migration to a fully stateless model, removal/deprecation of the Z39.50 and CORBA bindings, inclusion of OpenSearch compatibility, and support for the OGC modular specification approach for specifying requirements and conformance classes.

The new version of the candidate OGC Catalogue Service interface standard is available for comment below:

OGC Requests: 

Call for Participation in the CityGML 3.0 development

Status: 
Please note: This Request is scheduled to close on 10 June 2014.
Open Date: 
Mon, 05/19/2014
Closing Date: 
Tue, 06/10/2014 - 04:00
Description: 

This Call for Participation seeks organizations and individuals to participate in the development of the next major version of the OGC City Geography Markup Language (CityGML).

CityGML is a comprehensive open data model framework and XML-based encoding standard for the modeling, storage, and exchange of virtual 3D city and landscape models. Since 2008, it is an international OGC standard. CityGML is implemented as an application schema of the OGC Geography Markup Language 3 (GML3) Encoding Standard (http://www.opengeospatial.org/standards/gml), an international standard for spatial data exchange and encoding approved by the OGC and ISO. CityGML is being implemented across Europe, Canada, the Middle East and Asia. It has even been adopted by several countries including The Netherlands and Germany as official national and municipal 3D geo information standard, and it has been adapted as part of the European Union's common spatial data infrastructure INSPIRE.

Since the release of CityGML 2.0, a number of CityGML change requests have been submitted to the OGC. In June 2013, further requirements and ideas guiding the development of CityGML 3.0 were gathered and discussed at an international workshop jointly hosted by the OGC and the Special Interest Group 3D (SIG 3D). All presentation slides and the minutes of the workshop are available here: http://en.wiki.modeling.sig3d.de/index.php/Workshop_Munich_2013 . The outcomes of this ongoing discussion are formally captured in a list of work packages that define the overall work scope for CityGML 3.0. Examples of the identified work include changes to CityGML’s level-of-detail concept, additional semantic model structures such as building storeys, floor plans or utility networks, as well as new complex attributes like time series and metadata. To the extent feasible, new features will minimize impacts on backwards compatibility that might affect the many communities using the current version of CityGML.

The OGC solicits input and expertise from CityGML users, data producers, software vendors, and scientists in order to identify participants willing to contribute to and able to assume ownership for the work of the work packages under the joint leadership of the OGC CityGML Standard Working Group (SWG) and the SIG 3D. This call explicitly includes non-OGC members. Active participation in the CityGML 3.0 development process does not require OGC membership. To be most effective, organizations and individuals responding to this CFP should plan to fully participate in the CityGML 3.0 development activities.

The CityGML 3.0 work packages are as follows:

  1. Revise and maintain the UML representations of the conceptual model(s).
  2. Design and implement the standards document(s).
  3. Revise the level-of-detail (LoD) concept.
  4. Remove root-level inheritance from GML and separation of conceptual model and encodings.
  5. Develop a method to keep CityGML synchronized with changing GML versions.
  6. Develop a representation for changing content of entire models or parts of a model. This includes time-sequences of successive representations, simultaneously existing alternate versions, mobile objects, and dynamic objects.
  7. Develop a materials module and/or revise the textured surfaces module.
  8. Develop a representation for land administration.
  9. Develop a representation for non-building building-like structures.
  10. Develop a representation for utility networks.
  11. Develop a representation for volumetric construction and work toward harmonization with the Industry Foundation Classes (IFC).
  12. Develop representation for metadata, complex attributes, and harmonize with INSPIRE.
  13. Develop a representation for storeys (Am. “stories”) and other new semantic constructs.
  14. Develop or a mechanism for parameterized implicit geometries.

The work package list is publically available on GitHub at https://github.com/opengeospatial/CityGML-3.0/wiki. Interested parties are encouraged to register at the Wiki page of the work package(s) to which they wish to contribute by adding their

  • Name;
  • Organization(s);
  • Email address; and
  • Intended role (e.g., work package lead, editor, co-editor, contributor, reviewer)

to the list of participants.

Registration only requires a GitHub user account which can be obtained free of charge at https://github.com/join. The CityGML SWG intends to use GitHub as open platform for the management of work packages, discussion and issues, informative content, and publication of work results throughout the entire CityGML 3.0 development process. CityGML users are invited to use the GitHub platform to communicate existing or anticipated uses cases for CityGML to be considered in the development. If you are not familiar with GitHub, please contact the CityGML SWG Chairs who will assist you in registration.

Responses to the CFP are requested by the time of the 10 June 2014 kickoff of CityGML 3.0 development at the OGC Technical Committee meeting in Geneva, Switzerland. Note, however, that this CFP will remain open for the duration of the CityGML 3.0 development process.

About the SIG 3D

The SIG 3D is a special interest group of the German National Spatial Data Infrastructure (GDI-DE). The SIG 3D developed the first version of CityGML and in 2005 submitted CityGML as a candidate standard to the OGC. Subsequent versions of CityGML were jointly developed by OGC and SIG 3D based on a MoU between both organizations. The members of SIG 3D come from all over Germany and the bordering European countries. New members from anywhere in Europe are welcome.

About the OGC

The OGC is an international consortium of more than 480 companies, government agencies, research organizations and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that "geo-enable" the Web, mainstream IT, and wireless and location-based services. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.

The OGC invites comments on the candidate IndoorGML navigation standard

Status: 
Please note: This Request is scheduled to close on 21 March 2014.

Description: 

The Open Geospatial Consortium (OGC®) IndoorGML Standards Working Group seeks public comments on the candidate OGC IndoorGML Encoding Standard. 

The candidate OGC IndoorGML Encoding Standard has been developed to provide a common schema framework for interoperability between indoor spatial applications. These cover a wide spectrum of application areas such as indoor location services, indoor web map services, indoor emergency control, guiding services for visually handicapped persons in indoor space, and indoor robotics. Cross-platform, vendor-neutral communication of indoor spatial information is essential to meet the market demands of these applications. The international participants in the IndoorGML Standards Working Group have worked in collaboration with indoor navigation information standards groups in other standardization organizations including ISO/TC204 and IEEE Robotics & Automation Society (RAS).

IndoorGML is currently implemented as an application schema of the OGC Geography Markup Language Encoding Standard version 3.2.1. IndoorGML's minimal set of geometric and semantic data elements related to construction components is consistent with other standards such as the OGC's CityGML standard and buildingSMART's Industry Foundation Classes (IFCs). 

IndoorGML specifies conceptual models and XML schema based on cellular space representation for the following information about indoor space:

  • Geometric and semantic properties of spaces and connectivity
  • Navigation context and constraints
  • Space subdivisions and types of connectivity between spaces
  • Navigation networks (logical and metric) and their relationships 

The IndoorGML Standards Working Group (SWG) will consider all submitted comments for changes to the final draft of the IndoorGML Standard. The 30-day comment period ends March 21, 2014.

All OGC standards are free and publicly available at http://www.opengeospatial.org/standards. The candidate OGC IndoorGML Encoding Standard is available below:
